项目摘要
We have developed techniques for in-situ small-angle X-ray scattering measurement under high pressure. It is now possible to collect data for small samples in a diamond-anvil cell at a Q-range approximately from 0.1 to 2.0 nm-1. Three types of noncrystalline SiO2 have been measured so far with the new techniques and the following interesting results have been obtained; (1) the density difference between grains and grain boundaries did not completely diminish even at the highest pressure in experiments for silica glass and fumed silica up to 50 GPa and (2) the size of pores enlarged with increasing pressure in experiments for mesoporous silica up to 20 GPa.
我们开发了高压下的原位小角x射线散射测量技术。现在可以在金刚石砧池中收集小样品的数据,q范围约为0.1至2.0 nm-1。用新技术对三种非晶SiO2进行了测量,得到了以下有趣的结果:(1)在最高压力下,氧化硅玻璃和气相氧化硅的晶粒密度差和晶界差并没有完全减小;(2)在20 GPa下,中孔氧化硅的孔隙尺寸随着压力的增加而增大。
